Resolved questionsWhat honorific should I use while writing rules for students?

제가 1학년 초등학생들에게 영어를 가르치는데 이 학기 제 교실 벽에 수업 규칙을 게시되고 싶어요. Unfortunately, written Korean when giving rules and such is a little above my level. Should I write the rules politely or as more of a command? I see rules and such posted on the subway, but I haven't studied any of the rules. So far this is what I have, but I am not sure it is correct. Can you help me? Thanks !
